Two things to consider:
1. After the digital transition next week, there will be very few
stations left on channels 2-6. If there are none on these channels in your
area,
you can get by with a smaller antenna (element length), which will reduce
pickup at HF and 6 meters. Likewise, a HIGH-PASS filter cutting off just
below channel 7 (174 MHz) will be the ideal situation. This would also
reject two meter ham signals. I don't know if such filters are readily
available in the marketplace.
2. Non-linearity will be a potential problem in digital TV preamps. If
you are out in the weak-signal sticks, overload and non-linear response
aren't as likely to be a problem, but in areas close to the transmitters it
could be. You can have too much of a good thing with digital TV.

Actually, a digital signal is either real good or it is real

Here in the fringe area we need help to get the signal strength
we need for a consistent signal lock.
If I could find a mast-mount pre-amp which includes
bandpass and low-pass filters, to keep non-TV signals
out, then it should do a good job.
